MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Apr. 9, 1912.

Application filed November 8, 1910. Serial No. 591,267.

To all whom it may concern.

Be it known that I, CHARLES M. GREY, a citizen of the United States, residing in East Orange, county of Essex, and State of New Jersey, have invented a certain new and useful Mechanical Movement, of which the following is a specification.

This invention is a mechanical movement adapted for use in many arts.

Among the uses to which the invention may be applied are coin machines of various kinds, such as coin counting machines, coin assorting machines, coin or check controlled vending machines of many different varieties, telephone pay stations, etc. The movement is useful, also, in various locks.

Broadly stated, the invention is a mechanical movement embodying movable members dependent for their operation upon one or more, preferably two, dimensions of an operating member, such as a coin, a check, a key, or any analogous part, means actuated by said members whereby the movement thereof is aggregated or combined, and a transmitting member operable by said means, the total movement of said transmitting member being equal to the sum of the movement of the movable members.

The invention embodies other novel features of construction and combinations of devices as will be hereinafter described.

In the accompanying drawings I have illustrated one practical embodiment of the invention, but the construction shown therein is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure l is a side elevation of a mechanical movement embodying the invention, a side plate of a housing being removed, and certain parts being broken away and in section. Fig. 2 is an elevation with the side plate in position. Fig. 3 is a plan view.

A designates a main framework or housing of any suitable design, said framework operating to support the various working parts of the mechanism. As shown, the framework has a removable side, A, and said frame is constructed to accommodate substantially all the operative parts between or within its members. Within a slot, at, of said framework is positioned a group of primary operating members adapted to be actuated by an operating device of a suitable nature, the dimensions of which (thickness and width) vary. Said group of devices comprises, in

the embodiment shown, cooperating jaws, B, C, and contacting shoes or rollers, D, E. The jaws are, preferably, beveled on their opposing faces, at Z2 see Fig. 3, and they are retained normally in a cooperative relation, the space between the jaws being less than the diameter of a coin or check or the width of an operating member. Shoes, D, E, are, preferably, rollers positioned centrally in the space between the jaws, said rollers being normally in contact at their peripheral edges. Jaw, B, is rigid with a shank, b, which is slidably mounted in the frame, said jaw being rigid, also, with an upwardly extending arm, 5. In the upper end of this arm is fastened a rod, F, eX- tending horizontally through a part of the framework, the other end of said rod being attached by a pin, f, to the upper end of an upright lever, F. Said lever is fulcrumed intermediate its ends by a pin, f, in the framework. Jaw, C, is rigid with a slide, 0, the latter being supported in a suitable guide of the housing for endwise movement therein. Said slide is connected by a pin, c, to lever, F, the pivots, f, 0, being equidistant from the fulcrum, f, of said lever, F, whereby jaws, B, C, are adapted for simultaneous movement in opposite directions and to an equal extent. The two jaws are thus connected to a member, such as lever, F, common to both of them, and said lever is adapted to be moved by the con joint operation of the jaws. As shown, the fulcrum of the lever is at a point to produce two lever arms unequal in length, the longer lever arm being connected by a pin, 9, to a slide, G. Said slide is movable in a guide, 9, of the housing, said slide being provided at one end with a head, G. The head is slotted vertically, as indicated by dotted lines at it, the walls of the slot being perpendicular to the longitudinal aXis of the slide, and within the slot, at the back wall thereof, are positioned antifriction rollers, /t.

H, is a wedge block positioned within the housing for slidable movement in horizontal and vertical directions therein, said wedge block having an inclined face, H. The rear edge of the wedge block is vertical, and said wedge block is positioned for its rear part to occupy the vertical slot, it, in slide, G, whereby rollers, h, are adapted to ride upon the vertical rear edge of the wedge block during the vertical play thereof. The

wedge block is retained in cooperative relation to slide, G, by fitting said wedge block in the slot of head, G, thus precluding any sidewise disalinement of the cooperating slide and block. It will be manifest that movement of the wedge block in a horizontal direction is due to the movements of slide, G, and lever, F, said lever being operated in the first instance by the lateral or spreading movement of the jaws, the extent of which is dependent upon the diameter of a coin or check or upon the width of a primary operating member. Movement of the wedge block in a vertical direction, dependent upon the thickness of a coin, check or other operating member, is effected by the separation of shoes, 0, D, operating the following devices. Shoe or roller, D, is journaled for free rotation in the lower forked end of a vertically positioned bar, I, the latter being guided for sliding movement in a vertical direction within the housing. The upper end of said bar is shown as being provided with a knife edge bearing, 2', upon which rocks a lever, I, the latter being fulcrumed by a pin, i, to housing, A. The lever, I, engages with slide, I, at a point quite closeto fulcrum, i, and a long arm of said lever, I, is loosely fitted in a slot, 7', of a lifting rod, J, the latter being slidable in a guide, j, of the housing. Said lifting rod passes loosely through a vertical slot, 3' provided in wedge block, H, and said rod is provided with a collar, J, positioned for engagement with the lower horizontal face of the wedge block. The lower part of the lifting rod operates within a guide, 70, depending from the housing, said lower extremity of the lifting rod being provicled with a foot piece, 73 upon which acts a spring, K, the latter being coiled upon guide, is, so as to be retained in' position thereby. The vertical slot, jipermits wedge block, H, to slide in a horizontal direction relative to lifting rod, J, when said wedge block is acted upon by slide, G, the latter being operated by lateral movement of the jaws. Now, the lateral movement of the jaws is due to the insertion of an operative member between them, and such movement is dependent upon the diameter or width of such member; but the insertion of said Operating member actuates, also, the shoe, D, such movement of the shoe being dependent upon the thickness of the member wherebybar, I, lever, I, and lifting rod, J, are lifted. The elevation of rod, J, brings collar, J, forcibly into contact with the bottom edge of wedge block, H, thereby raising it relative to slide, G, but without removing it from cooperative relation thereto, for the reason that said wedge block slides within the slot provided in the head of said slide, the vertical rear edge of the wedge block riding upon antifriction rollers,-

h. It is apparent that the wedge block is movable in a horizontal direct-ion, and to a certain predetermined extent, by the lateral movement of jaws, B, C, which movement is transmitted through and multiplied by lever, F, acting upon the block through slide, Gr. Furthermore, the wedge block is movable in a vertical direction, and to a certain predetermined extent, by the lateral movement of shoe, D, relative to shoe, E, which movement of shoe, D, is transmitted through, and multiplied by, lever, I, acting upon rod, J, for lifting the wedge block. Accordingly, the wedge block combines or aggregates the movements of the two independent sets of primary operating members which are moved according to the different dimensions of an insertible piece, such as a coin or key. Thus, the separation of the jaws secures a movement of the wedge block for a certain predetermined distance, and the movement of shoe, D, relative to shoe, E, imparts an additional movement to the wedge block, or vice versa. Furthermore, lever, F, when operated by the lateral movement of the jaws acts to impart to the wedge block an increased throw or movement in a horizontal direction as compared to the movement of the jaws relative to each other; and, similarly, lever, 1, acts to impart to the wedge block an increased throw in a vertical direction as compared with the movement of shoe, D, relativeto shoe, E. In other words, levers, F, and I, act to multiply the relative movements of the jaws and shoes, respectively, thus increasing the extent of the travel imparted to the wedge block, such proportionately increased travel of the wedge block being desirable in order to move a transmitting member, L, through a wide radius of action for the proper operation of translating or subsequently effective mechanism of any suitable nature.

Cooperating with the wedge block, and operated thereby during either the horizontal or vertical movements thereof, or both of them, is a slide, M. Said slide is shown as having a head, m, fitted in a slot, m, of the housing, to guide the slide in a horizontal path. The head is forked, or provided with a vertical slot, 42, one wall, n, of which is inclined at an angle corresponding to face, H, of the wedge block, and within the slotted part of said head are anti-friction rollers, 0, positioned to ride upon the inclined face, H, of said wedge block. The slide, M, can move only in a horizontal path, relative to the wedge block, and said slide is retained in cooperative relation to said wedge block at all times by the forked or slotted head, m, embracing the wedge block, said slotted head sliding in the guide afforded by slot, m, of the housing. It is apparent that a vertical movement of the wedge block, due to the action of lifting rod, J, and lever, I, results in inclined face, H, of the wedge block riding upon rollers, 0, thus moving slide, M, in a horizontal direction. The movement of slide, G, in a horizontal direction by lever, F, acts to impart sliding movement in a like direction to the wedge block and to slide, M, whereby the wedge block and slide, M, are moved for a distance equal to the sum of the movements of levers, F, I, which levers depend for their action upon the dimensions of an insertible'operating member adapted to be positioned between the jaws and the shoes.

Slide, M, is provided with teeth, 29, forming a rack, said rack meshing with a gear, p, the latter being fixed to a shaft, P, journaled in frame, A. To this shaft is rigidly secured the transmitting member, L, herein shown as a toothed sector. This sector operates any kind of translating mechanism or subsequently effective mechanism, such as a lock works, vending mechanism, coin counting mechanism, coin assorting mechanism, telephone pay station mechanism, etc. As shown, the transmitting member meshes with a rack, Q, slidable in a guide, 9, said rack operating the translating or subsequently effective mechanism.

Shoe, E, is shown as a roller, journaled in a bracket, 6, fixedly attached to housing, A. As described, said shoe cooperates with shoe, D, carried by the vertically movable bar, I, but while shoe, E, is shown and described as occupying a stationary position relative to shoe, D, it is obvious that said shoe, E, may be movable.

Spring, K, acts normally to depress lifting rod, J, lever, I, and bar, I, for the purpose of holding shoe, D, forcibly into con tact with shoe, E. A spring, R, is employed for retaining jaws, B, C, in such positions that the space intervening them is less than the diameter of a coin or check, or than the width of an insertible operating member. As shown, spring, R, is connected to operate upon transmitting member, L, whereby the tension of the spring holds slides, M, G, and block, H, in contact, and said slide, G, acts on lever, F, to move the jaws into predetermined relation.

The operation will be apparent from the foregoing description taken in connection with the drawings. An operating member, of a kind suitable for use in connection with the mechanism, is inserted, by hand or otherwise, into the space between jaws, B, C, and shoes, D, E, whereby the jaws are moved away from each other for a distance representing the diameter or width of said insertible member and shoe, D, is lifted relative to shoe, E, for a distance equal to the thickness of said insertible member. The relative movement of the jaws turns lever, F, and shifts slide, G, to move block, H,

horizontally and for a predetermined distance, whereas the elevation of shoe, D, raises bar, I, lever, I, and rod, J, thereby causing collar, J, to move block, H, vertically and to a predetermined extent. Said block, H, is a common element acted upon by the group of primary members, 13, C, D, E, and the block operates upon member, M, to impart thereto a movement which is the sum of the aggregate movement of all the primary members multiplied in a fixed ratio by the leverage of levers, F, I, whereby an increased radius of action is imparted to transmitting member, L.

WVhile I have shown and described the novel mechanical movement as embodying a system of levers adapted to multiply the respective movements of the parts of primary operating members, it is to be understood that the invention is not restricted to multiplication of the relative movements of said primary members, for the reason that the movement may have its parts so organized and combined as to divide, add, or subtract in definite ratio. Furthermore, instead of employing a lever system for transmitting the movements of the primary operating members to a single element by which said movements are combined or aggregated, I may substitute therefor a system of wedges or a difierential gear, as exemplified in the mechanisms disclosed in a prior application for coin handling apparatus filed by me on October 17 1910, Serial No. 587,357.
